—In this paper, we present a sparse channel estimation method for orthogonal frequency division multiplexing (OFDM) based two-way relay networks (TWRN). Conventional channel estimation methods, such as least squares (LS), have been proposed to obtain channel state information (CSI) at the cost of the training resource, which reduce spectrum efficiency.(More)
This paper presents an ASP (application specific processor) with 512-bit SIMD (Single Instruction Multiple Data) and 192-bit VLIW (Very Long Instruction Word) architecture optimized for wireless baseband processing. It employs optimized architecture and address generation unit to accelerate the kernel algorithms. Based on the ASP, a multi-core baseband(More)
